FLUSHING-VALVE FOR WATEE-CLOSETS.

- Patented Feb. 4, 1908.

Application filed August 6. 1906. Serial No. 329.515.

To all whom it may concern:

Be it known-that 1, WILLIAM the King of Great Britain and Ireland, residing at Lambton Quay, Wellington, in the Colony of New Zealand, have invented. certain new and useful Improvements in Flushing-Valves for Water Closets, of which the following is a specification. 1

This invention for automatically provides improved means cutting oii the flow of flushing water passing to the pan of awater closet or the like.

According tothis invention a water supply pipe communicates with a valve chamber through which passes a valve rod, operable to a shaft, which passing box, enters a recess formed in a cap upon a down pipe, leading from the valve chamber. An arm secured to the shaftis connected to the valve rod by a coupling link. A stop valve fixed to the valve rod by a handle fixed downpipe, and below the stop valve a guide is providedior the valve rod.

A regulating chamber secured to the top of the valve chamber'has a perforated botshe t 5, passing throu tom plate, through which the valve rod passes. A perforated plunger, fitting loosely upon the upper part of the valve rod, rests upon a shoulder formed upon the rod, and has a valve seating for a regulating valve secured upon the end of the valve rod. The upper end of this rod is hollow and is perforated above its shoulder. A' regulating screw having a saw cut through its stem, screws into-the hollow top of the valve rod.

The top of the regu ating chamber is closed by a screw cap, whereby access is obtained to the regulating screw, and an escape fonair provided, when the valve is first brought into use.

The drawing herewith illustrates the invention.

Fi ure 1. is an elevation partly in section, and ig. 2. a sectional elevation of the flushing valve, and Fig. 3. is a sectional plan on line A-A. and Fig. 4. is a sectional plan on line B-B. Fig. 2.

Referring to the. drawin'szl is a Wail/8T supply pipe communicating with a valve chamber 2, through which passes a valve rod 3, oerable by a handle 4, which is fixed to a h a stufiing box 6, and entering. a recess 7 ormed in the cap 8,

1 allows the valve 7 has a seat in the valve chamber, vand a sleeve which enters the cap upon the ing up secured upon a down pipe 9. rod 3 by a con ling link 11, and ins 12 and 13. A stop va ve 14, integral with or secured to the rod 3, has a leather seating 15, secured in position by a sleeve 16, screwed upon the boss 17 of the said valve. The valve 14 has a seating 18, formedupon the top of the cap 8, and. entering the bottom or the valve chamber 2. When upon its seat 18, the sleeve 16 enters the top of the cap 8 into which it fits loosely and thus to close without sudden shock. A guide bar 19, is provided in the TURNBULL, g secured upon the shaft 5, is connected to the the valve 14 is closing cap 8 for the rod 3. The regulating chamber 20, is fixed upon the top of the valve chamber 2, and has a perforated bottom plate 21, through which the valve rod 3 passes.

plun er 22 having perforations 23, and fitting loose y upon the upper part of the valve rod 3, rests upon a shoulder 24, formed upon the rod 3, and has a valve seating 25 for a regu lating valve 26 screwed upon the end of the valve rod, and provided with a leather seating 27. The upper end of the rod 3, has a recess 28, and radial perforations 29 leading into the said recess. A regulating screw 30 having a saw cut 31, screws into the top of the recess 28, A screw cap 32- closes the top of the regulating chamber.

The flushing of a water closet if effected by raising the handle 4 to lift the valves 14 and 26 from their seats 18 and 25 respectively, to allow water to flow through the cap 8, and down pipe 9. The shoulder 24 raises the lunger 2.2,Which then passes upwards with the valve 26 raised from its seats 25 as clearly shown in Fig. 2, to allow free passage throu the plunger 22 of water contained in. t e upper part of tor releasing the handle 4, the valves 14 and 26 fall by gravity assisted by the flow of water through the chamber 2, and the descent of the valve 14 is checked by the valve 26 closon its seat 25,'and thus shutting off the flow of water through the perforations 23. Water below the plun or 22 then finds its way through the radia now exposed below the plunger 22,as clearly shown in Fi 1. The water finds its way through the holes 29 to the recess 28 and thence through the saw cut 31 in the screw 30'to the upper part of the regulating chamber.

The flowpf water and the descent of the plunger are regulated by adjusting the screw holes 29, Which,are

- bottom of the cap, and entering the valve chamber, a-

the valve rod, and means for 25 30, and thus exposing more or less of the saw cut 31 above the top of the valve 26. What I do claim and desire to secure-by Letters Patent of the United States is z- 1. For the purpose indicated, a flushing valve comprising in combination, a valve chamber, a downpipe cap' secured to the the valve chamber, a seating upon rated pl end 0 the valve rod and resting upon a shoulder formed on the valve rod, a valve seating upon the lunger, a regulating valve fixed to the top 0 the valve rod, means for reg latingthe flow of Water through the recess of operating the valve rod; substantially as set forth.

2. For the. purpose indicated, a flushing -valve comprising in combination, a valve chamber, adownpipe 'ca secured to the bot tom of the valve, cham er, a seating upon. the cap and entering the valve chamber, a regulating chamber secured to the valve chamber, a perforated bottom to the regulating chamber, a valve rod having'a recess in its up eating with the-recess, the said rod passing through the valve chamber and into the regulating chamber, asto valve Within the va ve chamber rigidly with the valve rod, a perforated plunger fitting loosely upon the upper end of the valve rod-and resting upon a s oulder formed an the valve rod, a valve lixed to t pins coupling the arm to per end and radial holes communiseating on the plunger, a regulating valve e top of the valve rod, a screw havmg a saw out through its stem and fitting the recess in the valve rod, ascrew cap closing the top of the regulating chamber, and means for operating the valve 'rod, substantially as set forth. g

3. For the purpose indicated, a flushing valve comprising in combination, a valve chamber, a downpipe cap secured to the bottom of the valvechamber, a seating upon the cap and entering the valve chamber, a regulating chamber secured to the valve chamber, a perforated bottom to the regulati g chamber, a valverodhaving a recess in ing, with the recess, the said rod passing through the valve chamber and into the regulating chamber, a stop valve Within the va ve chamber rigidly with the valve rod, a perforated plunger fitting loosely upon the upper endof the valve rod and resting upon a shoulder formed on the valve rod, a valve seating upon the plunger, a regulating valve fixed to the top of the valve rod, means for regulating its upper end and radial holes communicat the flow of Water through the recess of the valverod, a shaft entering arecess in the cap of the downpipe, a stufling box on the'down pipe and through which the shaft passes, a

andle upon the shaft, an arm Within the recess an fixed to the shaft, and a link and the valve rod, substantially-as set forth.

In testimony whereof I have signed my name to this specification in the presence of two itnesses. WILLIAM TURNBULL.
